For example, for a "Messages in Queue" metric for an autogroup of JMS Queues, the label above the chart is currently "Messages in Queue (JMS Queue)". Instead, it should be changed to something like "Messages in Queue (JMS Queue Child Resources)" or "Messages in Queue (Autogroup of JMS Queues)".

The chart labels on the Indicators page for a compatible group also need improvement. They always just contain the resource type name, whether the chart is for a compat group metric or a metric for one its members, e.g.:
Available Connections (Datasource)
Instead, for a compat group metric, I'd use something like:
Available Connections (All Datasources In Group)
and for a metric for one of the group members, I'd use:
Available Connections ('RHQDS Datsource' Datasource)
